My (old version) NXT wallet did the mandatory update and stopped working, it would hang on launch without any error message.
I deleted it and downloaded the 1.7.5 Mac wallet from nxt.org and that wouldn't even launch - would fail almost instantly with "An error occurred, the server has quit. Please restart the application."
Multiple restarts to no avail.
I downloaded the JLP version and it failed with the 404 error within my browser. I got it working by launching nxt.jar first and now it is downloading the blockchain.
Personally I am a long term NXT holder and have faith in the developers, but surely releasing buggy wallets isn't good for attracting new people to the community?
